well. people who go to usa feel the same way only it is reverse. my friend works there and he was shocked seeing how big the people are and just how much they eat fast food. he was working at some sandwich shop so he had seen it all.
i think its ok to experience culture shock but what it says about the country where the shock comes from fat people? i've had the experience when i was in egypt since there were a lot of black people. in my country there are some 10 maybe? ...you never see one (mby 5 times in my life)
i guess in a way it was the same as going to america and seeing XXXXL sized people - another thing that is not here...
